4.1.10 IEC Lead
Warning
Mains voltage applied to IEC Lead.
This test provides means of testing the continuity, insulation and polarity* of IEC test
leads.
Press
button (F3) to set the Pass/Fail limits for Continuity, Insulation and Test
Voltage. Use the up, down, left and right keys to highlight and set. The pass/fail limit for
the continuity stage can be calculated using the Calc button (F2). Enter the type and
length of cable and a new limit will be calculated. This can be overridden by selecting
the limit from the list. Press
(F4) when complete. Pressing the
button
(F3) will exit Settings mode without saving changes.
To perform an IEC lead test, connect the IEC socket side of the lead into the IEC inlet
plug of the Rigel 62353 Plus. Connect the mains plug side of the lead into the EUT
socket, of the Rigel 62353 Plus.
To start the IEC lead test, press the green START key.
The earth continuity resistance for the lead is measured using a ±200mA test current.
The display indicates the highest resistance and the pass/fail status. If this resistance is
less than the pass/fail limit, then the insulation resistance will be measured.
During an insulation resistance measurement, a high voltage is
applied between Live/Neutral and Earth of the IEC lead.
The insulation resistance of the lead is measured over a period of 2 seconds. The
display shows the final reading and the pass/fail status. If the insulation resistance is
greater than the pass/fail limit, then the lead polarity will be checked.
The lead polarity stage checks for short and open circuit conditions on the live and
neutral conductors. It also checks that the live and neutral wires are not crossed. When
testing non-polarised IEC leads (e.g. Schuko mains leads) Live and Neutral can be
crossed without implications. As such, this feature is excluded where applicable.
